Method for producing protective drainage wraps
View Patent ↗A protective drainage wrap comprises a first portion, a second portion and a solid sheet portion. The first portion comprises cross-woven or cross-laminate material in the machine direction and in the transverse direction. The material in the machine direction comprises a polyolefin, polyester, nylon or combinations thereof and has a first thickness. The material in the transverse direction comprises a polyolefin, polyester, nylon or combinations thereof and has a second thickness. The second thickness is at least about 2 times greater than the first thickness so as to assist in providing drainage for moisture build-up. The second portion is a coating comprising a polyolefin, polyester, nylon or combinations thereof. The first and second portions are located adjacent to each other. The solid sheet portion comprises a polyolefin, polyester, nylon or combinations thereof. The solid sheet portion is attached to at least one of the first portion and the second portion.

9. The method of claim 1 , wherein the machine direction material has a machine direction count of from about 6 to about 24 per inch and the transverse direction material has a transverse direction count of from about 3 to about 6 per inch.
10. The method of claim 1 , wherein the machine direction material, the transverse direction material and the coating comprise a polypropylene, polyethylene or combinations thereof.
11. The method of claim 1 , wherein the transverse direction material is yarn.
12. The method of claim 11 ,wherein the yam is spun yam, bulk continuous process yarn or natural yam.
13. The method of claim 11 , wherein the first portion is cross-woven.
14. The method of claim 11 , wherein the first portion is cross-laminated.
15. The method of claim 1 , wherein the second thickness is at least about 4 times greater than the first thickness.
16. The method of claim 1 , wherein the solid sheet portion is a breathable film.
17. The method of claim 1 , wherein the solid sheet portion is attached to the first portion.
18. A method of using a protective wrap in a building, the method comprising: providing a protective wrap comprising a first portion, a second portion and a solid sheet portion, the first portion comprising cross-woven or cross-laminate material in the machine direction and in the transverse direction, the material in the machine direction comprising a polyolefin, polyester, nylon or combinations thereof, the machine direction material having a first thickness, the material in the transverse direction comprising a polyolefin, polyester, nylon or combinations thereof, the transverse machine direction material having a second thickness, the second thickness being at least about 2 times greater than the first thickness so as to assist in providing drainage for moisture build-up, the second portion being a coating, the coating comprising a polyolefin, polyester, nylon or combinations thereof, the coating comprising a polyolefin, polyester, nylon or combinations thereof, the solid sheet portion comprising a polyolefin, polyester, nylon or combinations thereof, the first and second portions being located adjacent to each other, the solid sheet portion being attached to at least one of the first portion and the second portion; providing a sheathing; and installing the protective wrap over the sheathing.
19. The method of claim 18 further comprising providing an exterior covering selected from siding, brick, masonry, stucco or concrete veneer and installing the exterior covering over the protective wrap.
20. The method of claim 18 further including providing at least one framing member, the sheathing being located between the protective wrap and the at least one framing member.
21. The method of claim 18 , wherein the protective wrap is perforated.
22. The method of claim 18 , wherein the first portion is cross-woven.
23. The method of claim 18 , wherein the first portion is cross-laminated.
24. The method of claim 18 , wherein the machine direction material and the transverse direction material comprise a plurality of tapes.
25. The method of claim 18 , wherein the machine direction material has a machine direction count of from about 6 to about 24 per inch and the transverse direction material has a transverse direction count of from about 3 to about 6 per inch.
26. The method of claim 18 , wherein the machine direction material, the transverse direction material and the coating comprise polypropylene, polyethylene or combinations thereof.
